Headend facilities and hub sites are cornerstones of the broadband network. Because they are so vital to our communications needs, these facilities are designed to never fail. The foundation of that reliability are the power and energy conversion and storage systems.

Headend and hub locations must operate 24/7 even when the electrical utility grid is down. Without them, broadband networks go dark and tens of thousands of customers lose communications. These locations house a variety of communications and computing equipment of varying ages making powering requirements diverse. Power systems must support equipment requirements for AC and DC loads. Engineering the correct energy solution for each facility ensures reliable and redundant power all the time, every time.

Implementing Nanogrid into the Critical Facility


Implementing Nanogrid into the Critical Facility

Operators are looking at introducing nanogrid architectures into critical facilities to maintain reliability in the face of increased thermal loading and to eliminate points of failure. Nanogrid architectures will further enable the use of distributed energy resources (DERs) such as wind or solar to supplement utility power, allowing operators to realize additional cost benefits by avoiding peak usage utility rates or selling power back to the grid.
